Product Features

1. The housing is constructed using high-strength SMC compression molding. The transparent cover is made of polycarbonate injection molding, offering excellent light transmission and high impact resistance;

2. The housing features a labyrinth structure, providing effective dustproofing, waterproofing, and resistance to strong corrosion;

3. The internal ballast is a specially designed explosion-proof unit with a power factor ≥0.95. It incorporates a built-in disconnect switch that automatically cuts power when the housing is opened, enhancing safety. Features short-circuit and open-circuit protection, along with circuits to counteract lamp aging and gas leakage, ensuring reliable operation. Offers wide voltage input range, constant power output, and high energy efficiency;

4. Equipped with renowned brand fluorescent tubes for extended lifespan and high luminous efficacy;

5. Emergency lighting system configurable upon request. Automatically switches to emergency mode during power outages;

6. Compatible with both conduit and cable wiring.
